Specification of Letters Patent. Application filed July 23,1906. Serial No. 327,288.

Patented Aug. 6, 1907.

'o all whom'it may concern:

Be it known that I, WILLIAM L. Mruon'rr, a citizen of the United States, residing at Ann Arbor, county of Washtenaw, State of Michigan, have invented a certain new and useful Improvement in Oilers; and declaro the following to be a full, clear-,and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to oilers, and consists in the improvements hereinafter described and pointed out in the claims.

In the accompanying drawingsz-Figure l, is a sectional elevation of a device embodying my invention. Figs. 2, and 3, are details illustrating the operation of the apparatus for adjusting the rate of leed. Fig. 4, is a plan view of an oiler embodying my invention. Fig. 5, is a section on the line 5 5 Fig. l. Figs. (i, 7, 8, and 9, are sections on the line 6`G Fig. l; a portion of the lever O by which said valve is adjusted to different angular positions being also shown, and the valve being shown inits different operative positions. Fig. l0, is a vertical section on an enlarged scale through the axis of the feed valve in the position shown in Fig. 9, showing parts adjacent to the feed valve in section.

Referring to Fig. 1, C is the usual glass cylinder used in oil cups. A is a base, and B a cap. The base A and cap B are drawn together by a coaxial tube D united to thebase at its lower end, and provided with a nut E at its upper end, thus closing the ends ofthe cylinder C. The nut E may be screwed down on the threads on the tube D against the cap `B, or against a washer on said cap.

In the base A is formed, coaxial with said base and the cylinder C, a cavity bounded by conical walls c.

'This cavity opens by an aperture a through one of its walls to the interior of the cylinder C, which cylinder with the base and capiattached, as liereinbef nc described, forms a reservoir for oil. l

b is an aperture axially in line with, and opposite to, the aperture a. The aperture b opens to the exterior of the base A, except that in its outer end is a nipple X, which forms a means of communication to a source of oil supply, not shown in the drawings. lhe conical Walls c diverge downwardly.

L is the feed valve. This is formed with conical walls adapted to tit against the walls c.

' e is a vertical passage in, and coaxial with v.- the valve L.

f, f, are passages through the valve L, at right angles to the passage c, and communicating with said passage.

i l i' g i l j l l l I l f i l f, f, but located at different angles and extending from the periphery of the valve L to its center. All the passages f, f, g, h, communicate with the upper end of the passage c. There is a conical valve seat (l-formed at the upper end of the passage e.

M is a tube coaxial with the cylinder C and valve L, rigidly connected to said valve at its lower end. The tube M extends through the cap B.

O is a lever arm connected to the tube M at its upper end so as to be capable of moving longitudinally with reference to said tube, but restrained from angular nut N is located above the lever arm O. By screwingdown upon the nut N the tube M is drawn upward and the valve L drawn firmly against its seat.

I is a hardened steel conical valve adapted to seat upon the valve seat d to close the upper end of the passage c.

R is a rod extending axially in line with the valve B, v and coaxial with the cylinder C through, and above, the upper end of the tube M.

Q is a sleeve adapted to fit and slide in the tube M, and te forni a piece joining the valve P, and rod R, which are fixed to said-sleeve.

V is a packing gland surrounding the rod R, and U is packing material above said gland. I

T a nut having a milled head, and provided with exterior screw threads engaging the interior screw threads in the upper end of the tube M. The nut T forms a second gland for holding the packing material U.

W is a helical spring resting at its lower end against the sleeve Q, and at its upper end against the gland V. The packing material U is compressed between the gland V and the nut T to form a tight joint.

S is a cam lever pivoted to the upper end of the rod R and provided `with two cam faces adapted to engage the top of the nut T to draw upward'on the rod R, lifting the valve P from its scat different distances when said lever is turned to different positions, as indicated in Figs. l, 2, and 3, to cause the different faces to engage said nut. t

F is a downward extension from, or an attachment to, thc base A, adapted to serve for a means of attaching the oiler in position. projection F from the passage e to the delivery end of said projection. Between its ends the projection F is cut away upon opposite sides as indicated in Fig. 5. Toward-the upper end ot the projection F is an interior bearing'snriace supporting the packing ring J. y

H is a nut having a passage through it and having ex- There is an axial passage through the 1 Q0 'I i l E terior screw threads engaging interior screw threads in the projection F, toward the lower end thereof. The nut H is provided with a bearing surface supporting a packing ring l1. I

Gisa glass cylinder, its upper end resting against the packing ring Jl. By turning the nut I-l, the cylinder G is forced lirmly against its packing rings, so that tight joints are formed at the end of said cylinder.

Y (Fig. 4) indicates an opening by which the cylinder C may be supplied with oil from a can. l, 2, 3, 4, in said figure indicato notches in the cap B, into which a spring pawl or detent on the end ot' the lever O engage at the different Operative positions. The reference numerals l, 2, 3, 4, may, therefore, be used to indicate these different operative positions of the lever O and valve L.

Z, is a passage-way formed obliquely through the valve L. The lower end ol said passage-way opens at the lower end ol' the passage c, and the upper end of said passage is adapted to be put into communication with the aperture a when the valve L is turned to the position indicated in Fig. 9.

The operation ol the above described device is as follows The nippleI X isconnected with a source of oil supply. When the level' O is turned to position 1, as indicated in Fig. 4, the passages f, f, put the apertures a and b into communication` and the oil runs from the source of supply into the cylinder C lo lill the reservoir ol the oiler. When the level' O is put into position 2 (Fig. 4) the valve L is in the position indicated in Fig. 7, in which ease the aperture I; is closed, shutting off the supply ol oil. and the passage h connnunicates with the aperture a. so that when the valve P is raised, oil will llow from the reservoir ol the oiler through the passage c to the place ol application. rlhe rate of feed may be observed by looking through the glass oi the vcylinder G. When the level' O is turned to position 3 (Fig. 4) the valve L is in the position indicated in Fig. S, in which the passage l1. pills the aperture l) into communication with the passage c when the valve l is raised, so that oil may llow from the source ol` supply directly to the place ol applical ion, without lilling the reservoir of the oiler. \\'hen the lever arm (l is turned to position 4 (Fig. 4) the valve l. has the position indicated in Fig. l), and also shown in Fig. l0, in which the source of supply is put into communication with the point ol application through the aperture b, passages g and e, and at the same time the passage Z communicates with the aperture a, so that the reservoir of the oiler is in communication with the point ol application ol the oil. Thus, in this position. two kinds of oil can be fed at once, one from the reselvoir through the passage Z, and the other from the source of supply through the passage c.

ln the position of the lever S, shown in Fig. l, the valve P is closed upon the conical seat rl, held thereto by the spring 1V, and the passage a is thereby closed. When said lever is turned to the position shown in Fig. 2, the rod R is drawn upward, raising the valve P slightly from its seat, and opening the passage c. -When the lever S is turned to the position shown in Fig. 3, the Valve P is drawn a considerable distance from its seat, leaving the passage e wide open. This latter' may be called the emergency position, a position for feeding oil rapidly under unusual circumstances, such as to supply a hot beari ng.

It will be observed that with the various utilities above pointed out, the apparatus has the appearance of an ordinary oil cup.

The valve L is made of brass or other soft material, so that the valve seat d is of such soft material. The valve P is of hardened steel, It is a small piece of metal, and can be properly tempered or removed and replaced.

If there is a pressure upon the oilAsupply, the oil may be fed from said supply, as required, and without danger of leakage.
